Marine Cargo and P&I Insurance: A Buyer's Guide to Global Underwriters
The marine insurance market reached a record $39.92 billion in global premiums in 2024, with cargo insurance alone valued at over $20 billion. For ship owners and marine risk managers, navigating the landscape of underwriters is essential to securing competitive coverage across hull, cargo, and liability exposures.
The International Group of P&I Clubs
Protection & Indemnity insurance is dominated by the International Group, a not-for-profit association of 12 mutual clubs covering approximately 90% of the world's ocean-going tonnage. These clubs pool large loss exposures above retention levels, providing ship owners with coverage that no single insurer could underwrite alone.
| P&I Club | Country | Notable Scale |
|---|---|---|
| Gard | Norway | Largest IG club, ~50% of global merchant fleet |
| NorthStandard | UK | Formed from merger of North and Standard clubs |
| Steamship Mutual | UK | 9,000+ vessels across 50+ countries |
| Skuld | Norway | International marine mutual since 1897 |
| Japan P&I Club | Japan | Major Asia-Pacific coverage |
| The Swedish Club | Sweden | Strong Nordic and tanker presence |
Commercial Cargo Underwriters
Beyond the mutual P&I system, the commercial cargo market features global insurers and Lloyd's syndicates competing on price, breadth of coverage, and claims service. The largest cargo markets by premium volume are China (17.6%), Lloyd's (9.7%), and the US (6.9%).

What to Consider When Selecting an Underwriter
Choosing between a P&I club and a commercial underwriter depends on the exposure profile. P&I clubs offer mutual pooling for liability risks — crew injury, pollution, wreck removal — while commercial markets handle first-party cargo and stock throughput policies. Many ship owners maintain both: a P&I club membership for third-party liabilities and a commercial policy for cargo-in-transit exposures.
Key evaluation criteria include financial strength ratings (AM Best, S&P), claims settlement speed, loss prevention services, geographic network, and the underwriter's appetite for your specific vessel or cargo class.
